Abstract:
Objective:To analyze the urodynamic and clinical features of detrusor underactivity(DU)in elderly men aged 60 years and over.Methods:Five hundred and seventy-three men aged 60 years and over underwent urodynamic measurements due to dysuria were retrospectively analyzed.According to the urodynamic parameters of bladder contractibility index(BCI)and bladder outlet obstruction index(BOOI), they were divided into the three groups: only detrusor underactivity(DU group)(BCI<100 and BOOI<20), only bladder outlet obstruction(BOO group)(BCI≥100 and BOOI≥40), and the combined non-DU and non-BOO group(NDB group)(BCI≥100 and BOOI<20). The urodynamic and clinical features were compared between the three groups.Results:The internalized 323 patients meeting inclusion and exclusion criteria were divided into 3 groups: 75 in the DU, 207 in the BOO and 41 in the NDB.The age was higher in DU and BOO groups than in NDB group( P<0.05). The DU group versus the NDB group showed the higher levels or values in the volume at first desire(FDV)[(279±80)ml vs.(238±72)ml], the proportions of incomplete bladder emptying(41% vs.17%), urine flow interruption(39% vs.15%)and retention(26% vs.7%), and the lower levels in the voiding efficiency(VE)[(61±32)% vs.(110±41)%], (all P<0.05). The DU group vs.the BOO group showed the increased levels or values in the FDV[(279±80)ml vs.(206±67)ml]and maximum cytometric capacity(MCC)(353±113 ml vs.281±94 ml)and the proportions of urine flow interruption(39% vs.22%), TURP(26% vs.6%), and retention(26% vs.14%), and the decreased levels or values in the VE[(61±32)% vs.(78±37%)], the proportions of DO(41% vs.77%), urgency(26% vs.43%)and nocturia(23% vs.39%)(all P<0.05). Conclusions:The main urodynamic and clinical features are manifested as the reduction of bladder sensation and bladder emptying rate, urine flow interruption, urinary retention and having a TURP history in elderly man with detrusor underactivity.The proportions of DU and BOO are increased along with aging.
